OH, and ladies...
if you haven't made plans to be part of the Nebraska State Time Trial,
you should do so. The registration says open women I think, but cat 4 will be separate. Time trials are a great way to try out the racing thing because you don't have to deal with pack dynamics. You should also keep in mind that bike racing is for folks of ALL ages. Come on out and have some fun. Racing is a great way to motivate yourself to reach your fitness goals as well as meet other people one the same wavelength.
